Hifiman EF-5 headphone amp upgrade with Burson Supreme Opamps

I installed your Supreme Sound opamps for Hifiman EF 5 – headphone amplifier. I replaced it for IC opamp OPA 627 BP. After burn the system (about 40 hours) to clear sound across the spectrum, significantly raised dynamics, and show musicians in space is much more accurate. I took your scaled Sound opamp 4th generation, so I placed it at the socets IC opamp. I had in a plastic housing EF 5 hole cut to them passed your opamp. Result you can see in my photos.

I think it looks interesting and unconventional. It’s the only way into the headphone amplifier to get you a great discrete amplifier.

Great combination. Thank you for a great product, I definitely recommend!
